desired. The. invention also relates to ma-' chines for rubbing down the stitches, par ticularly in welt shoes, before the tread channel flaps are closed. f i

In: the art there have been a number of different types of machines for this type of work, but withthe'development of present styles, particularly in welt, shoes, the'rnachines referred to .do not seem entirely suitable. In the manufacture of weltshoes it is customary to form a thin channel flap on the tread surface of the ,outso'le close to the outer edge, and after thestitching operation which secures the outsole to the welt is completed', this flap is closed down'to conceal the stitches.

" I propose to guide by combining-with the shank breaking tool an independent guide which maybe moved along'the root or-outer base of the tread channel flap. Ordinarily an angular shoulderis formed "between the flap and thechannel, and it is the object of myinvention to provide a guiding device which will function along this shoulder. As the beating iron may extend the full width of the channeled edge at its widest point,

it will merely protrudeover the edge in narrower portions without causing damage.

I further ihave,"as'an object, the combination with the beating tool and the guide of a guard which will insure prote'ctionto the shoeif the operator should, during the operation, allow theshoe :to runout of alignment with the guiding device. It is my object to provide a guard or guardson the sides of a breaking tool and to also providea guide which, when theoperator holds 'theshoe with the mainbody of the shoe sole extending either inwardly or outwardly from underneath the breaking ironywill positively protect the shoe or sole on the sides "of the heating tool. p ff- I s It is further my object to so mount the guide that it will give with pressure of-the shoe bottom against the tool,and "which also may be adjusted sothat theoperator can carry out the beating operation holding the shoe at a desired angle.

The above and other objects to which reference will be made during the ensuing disclosure 1 accomplish by that certain combination and arrangement of parts of which I have shown 'a preferred embodiment.

In the drawings Figure l is a side elevation of the head of I 7 my improved shank breaking and stitch rubbmg niachlne.

Figure 2 1s an end elevation of the head shown 1n Figure 1.

a Figure 6 is a side elevation of an improved type of breaking iron with the outside face having the same curve as the finished surface of the channel.

a The machine is usually .mounted on a standard or base on which either a driving pulley or amotor is set. These partsare not illustrated as they form no part of my invention.

I have indicated at 11 atubularpedestalin which the head 12 of the machine Qisladjustably mounted. On the head of the machine there are a pairof journal boxes 13, 1a, which journal the shaft 15 which carries the beating iron. The shaft 15 is operated by abelt 16 which passes about a pulley 17 which is secured on the shaft. The end of the shaft opposite that on which the pulley 17 is mounted is tapered and recessed as indicated. On thev tapered end of the shaft in annular channeled )ortion 19 I have shown the ,freely mountedsleeve 20, which is of such diameter as to provide clearance for the channel flap.

1 The beating tool generally indicated at 21 has a recessed end'22 which is engaged by the head of a screw 23 threaded in the end of the shaft 15.. In the modified type shown in Figure 6 we have indicated a tool having a heating surface contoured to theshape of the finished channel. Interspacing the sleeve 20 and the beating iron 21 I have shown my novel guide which consists of a thin plate 2 L extending slightly beyond the outer extremities of the beating tool. The plate24 has a centralopening which clears thefshaft 15, thereby allowing resilient movementjo-f the plate, For supportingthe plate'I haveshown an arm 25mounte'd on aboss26on an adjustable auxiliary bearing member 27.:;Th'e arm I 25 is" preferablyformed integrally with the plate 24.

As a guard to prevent damage by the tool becauseof the shoeslipping out from under the tool I have shown in addition'to the guarding sleeve 20, the guard 28 which is countersunkasindicated at 29 and clears the innersurface of the head of the screw 23,

thereby permitting the I guard to be carried in a freely. rotatable positionin The outer periphery of the guard 128' is "of such dimensionas't'o lie substantially in alignment with the outer extremities of scribed.

are of concave shape so that to lie downsnugly against the b j upper. With my new 50" the shoe ina clockwisedirection, as indicated in Figure i, and bearing'up against the tool, the channeled edge is beaten over so as to close the gap between the upper surface of the welt and the outer surface of the upper. In breaking the channeled edge of the shank and thechanneled portion of the tread of the sole theoperator usually starts in close to the heel and bears upwardly with the shoe while .he advances the channeled edge along with thethin edge 31 ofthe guide passing along against the angular'shoulder of the channel flap. When the operator has reached the tip of "the sole he turns the shoe around in his hands and beats down the other edge of the sole in'a similarinanner'. g The guard 28 prevents the 's'hoefrom coming in contact with the, rotatingbeating iron in case the shoe shou'ldslip from the position in which it is held against the beating-iron. LIf the shoe should slip in the other direction,no harm willresult as all that will hap pen in this contingency willibel for the shoe to rub against the freelymounted sleeve 20.

f Modificat ions in structure will readily occur to those skilled in the fart in which the support for the guide andthe particular journal supportand'mechanical correlation of parts is varied, but in so faras machines are built which guide by means of the angular shoulder formed by the channelfiap, I c0nsider such modificationswithin'the'scope of my invention.
